English FA Cup
12:00 +00:00, February 17, 2013
Stamford Bridge, England
Referee: N Swarbrick
FULL TIME - Douglas sits on the ball inside his own area to keep the score at four and that is that. Chelsea go through but Brentford gave a good account of themselves. Chelsea travel to Middlesbrough in round five.
A late flurry from Brentford as Saunders tries to work space for a shot. Luiz hammers behind for a corner.
Good noise from the Brentford fans as their cup adventure comes to an end.
Four minutes added. Not quite sure why...
Things petering out now....
Reeves goes straight off an down the tunnel and the more you look at that incident the worse it becomes. Luiz is a lucky lad because that was very nasty indeed. No need for it either.
That is a red card. Luiz has stuck his shoulder right into Reeves' face and he looks a little concussed. That was cynical and very dangerous.
Luiz gets a yellow card for a late elbow on Jake Reeves. That was extremely nasty.
It'd be nice for Brentford to get a goal wouldnt it?
A lovely goal too - a super ball to the back post from Oscar and a brilliant header from Terry creeps in at the foot of the post.
GOAL Terry grabs a goal!
And that is Lampard's last involvement - he's replaced by Ryan Bertrand.
Oscar tries to play in Lampard but he hasn't got the pace to drive into the box. He wins a corner.
Forshaw departs and Sam Saunders gets 12 minutes to make a name for himself. A quick hat-trick should do it.
Torres looks relaxed on the bench.
Yossi Benayoun is coming on for Mata, who looks disappointed to be coming off.
Bidwell crosses right into Cech's arms. Brentford well need to work hard to prevent more goals in the final stages now.
That is harsh on Brentford really, as they've done well. They made a change in the wake of the goal, Reeves replaces Diagouraga.
A superb assist from Mata as he dinks a superb cross over the first man for Lampard to fire home from seven yards. He is now Chelsea's all-time leading FA Cup scorer.
GOAL Lampard turns home number three!
Donaldson meets a Brentford corner from six yards but it hits his shoulder and flies over the bar.
Ivanovic is booked for felling Forrester.
Hazard gets to the edge of the area, feeds the overlapping Ivanovic and Oscar's flick somehow bobbles into the net past two defenders and the goalkeeper.
GOAL Oscar wraps the tie up!
Don't forget we have commentary on Man City v Leeds coming up at 2pm GMT - in about 35 minutes. Joe Hart and Gareth Barry don't feature at all for City.
A reminder that Middlesbrough await the winner of this tie.
Victor Moses is the man who makes way for Hazard.
Hazard about to come on.
Donaldson is flagged offside now as Adeyemi looks to find him. Close call.
Ba is flagged offside from a Moses pass over the top.
Brentford are briefly two on two as Donaldson wins the ball but his ball for Forrester is marginally over hit and takes him wide where Terry mops up.
Now Adeyemi wins a corner. Brentford's fans roar them on, all 6,000 of them.
Forrester, who is on for Trotta, wins a free kick wide left.
Now that changes the complexion completely, as Brentford will have to alter their approach a little. They'll have to come out a bit more now.
And that came out of nowhere really! A long ball is flicked to Mata, who latches onto it and fires a shot past Moore from 20 yards. The bounce did for the goalkeeper.
GOAL Mata breaks the deadlock!
Dogged defending from Brentford as Douglas blocks Cahill's volley.
Moses gets in the box now on the opposite side but he can't pick out a ball either. Corner.
Great run from Oscar, up the byline almost to the edge of the six yard box but not a great ball across to try and find a team mate.
Chelsea have emerge with a bit more intensity about their football.
Decent chance for Ba at the back post as Chelsea put Brentford under pressure. Hacked clear.
Good tackle from Logan as Lampard went into the area. He wins a goal kick too. Well played.
We begin again....
Oscar hit the post for Chelsea during their FA Cup fourth round replay against Brentford
HALF TIME - and there is the whistle. Chelsea should be in front, Lampard and Oscar missing good chances, but Brentford have done well and had fleeting moments of clarity in Chelsea's half. They'll be delighted with the scoreline and their performance so far.
Good run from Donaldson down the left and a nice cutback but Adeyemi's shot is blocked by Terry. Corner.
Oh it should be 1-0 and again Lampard has fluffed his lines. From Ivanovic's cross, eight yards out, he's dragged a volley wide. You expect better from him.
I like the look of this Brentford side, they are well balanced and not afraid to play. Douglas is now stopped in his tracks by the ref's whistle.
A proper reducer between Oscar and Diagouraga. Brentford get the decision, which delights their fans.
Both Forshaw efforts from the free kick are blocked by the wall. Neil Swarbrick has had a poor half with the whistle. He could have waited a second or two to see if there was an advantage.
Ooh, controversy, Luiz clips Forshaw and the foul is given, then Trotter marches through to score after the whistle had gone. Poor refereeing there, should have played advantage.
Thankfully justice is done as Moore claims Cahill's flick after Lampard's initial delivery was nodded into the air by Douglas.
In fact, the ball hit Cole in the knackers, that's why he went down.
Now Cole wins a free kick from Logan when there was no contact at all. Big side getting all the decisions here.
Another free kick given against Douglas - ironic given the one that wasn't given against him was the worst of the game so far.
Both Avram Grant and Claudio Ranieri in the stands. Is Roman having a reunion?
Now at the other end Forshaw has another go on goal, this time with his left foot and he drags it two yards wide of the post.
That's better from Ba as he gets into the area, Douglas tracked him and slid in to block the shot before Moore pounces on the ball.
Ba flicks on to no-one in particular.
Simon Moore asked for a cap to deal with the sunshine. An eager backroom member brought it over and now he doesn't want it! Charming
A poor free kick from Mata is cleared but Terry wins a header as the home side regroup.
Having said that Brentford will be reasonably happy with how it has gone so far. They've limited Chelsea to only a few good openings.
That's the best chance of the half so far and Chelsea should be in front.
Off the post! Oscar should score as he is fed by Mata. The ball is a yard out of his reach and he can't wrap his foot round it but still hits the upright.
Fantastic ball from Mata right across the face of goal, everyone missed it apart from Ashley Cole at the back post but he chips it way back over everyone's head.
Well done Donaldson, tracked Ivanovic all the way and nudged him off the ball from Moses' pass.
Another wayward effort from Lampard as Mata teed him up. A difficult one to hit with the ball coming across his body.
Good run from Luiz, a good cross to match and another good clearance from Dean. Good good.
A3 poster held up inside the ground near the press box reads: "Rafa Benitez, worst manager since Mr A took over, FACT Benitez out," reports one journo.
From the corner Luiz's ambitious effort flies wide.
What a block by Dean! Moses gets round the back, pulls the ball back and Lampard scuffs it, but the ball breaks for Oscar who would have scored but for a lunging block from Dean. Superb defending.
Lampard's hopeful ball is knocked out by Bidwell.
Our commentators didn't even pass comment on that awful Cahill tackle. The inevitable Di Matteo chants ring round the ground. It is 16 minutes after all.
A free header from Ba as Oscar crosses and he should have done better with that.
Chelsea work the ball down the right and win a corner.
Now Douglas is caught late and very nastily by Cahill. Very poor tackle but not even a card for Cahill. That was a shocker.
Ivanovic crosses and Dean clears.
Now a chance for Brentford as Donaldson gets a free header from Logan's cross. He was about 14 yards out but dribbles his header wide.
Mata's free kick is deep to the back post and Ivanovic's nod back across goal loops over everyone and past the far post.
Brentford's fans howl as Bidwell tugs back Moses by the corner flag and the free kick is given.
Forshaw has a pop from range and it isn't too far away from the far post. Cech wasn't perturbed though.
Ba is wearing a snazzy mask - a legacy of that challenge from former colleague Coloccini.
As you'd expect Brentford are taking a safety first approach, sitting deep in the early stages.
What a day out for Brentford's fans too - they are in full voice already.
Donaldson brings the ball forward and holds off Luiz, until the Brazilian nudges him to the floor. No foul given from the referee though. He's obviously still got some sleepy dust in his eyes.
A nice feint from Moses brings a foul from Bidwell. Oscar's cross takes a deflection and Moore takes it well in front of his line.
It's a glorious day for football - bright and sunny and about nine degrees. Let's hope for a cracker.
